To all whom 'it may concern:

Be it known that I, JAMES L. NEWELL, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented new and useful Im rovements in Pneumatic Tires, of which t e following is a specification.

This invention relates to improvements in pneumatic tires, particularly tires of that class which are used on the wheels of automobile vehicles, and the said invention consists in the construction, arran ement and combination of devices hereina ter described and claimed.

'One obiect of my invention is to provide nove means to prevent the tire from being punctured.

Another object is to provide means to protect the periphery of the tire' from exoesssive Wear.

A further ob'ect is to provide means for strengthening t e construction of the tire.

In the accompanying drawings, Figure 1 is'a plan of a portion of the periphery of a tire constructed in accordance with m invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a detail elevation of the reinforced plates which are embodied in the fabric of the tire. Fig. 4 is a plan of the same.

In accordance with my invention, the tire 1 which is made of rubber or other suitable material or of rubber reinforced. with canvas or other suitable fabric and which is here shown as of substantially horse-shoe shape cross-sectionally, but may be of any other suitable shape, comprises an outer portion 2 and an inner portion 3. In the space between said outer and inner portions is ari armor which comprises plates 4 and 5. The plates 4 are curved transversely to conform to the shape of the outer portion of the tire and are provided at their ends with rolled portions 6, which form interlocking hooks 7 so that the said plates 4 are detachabl connected together end for end. The sai lates 4 are made of suitable metal, such or instance, as sheet aluminum of an suitable thickness and are provided at thelr.

sides with hin e membersA 8. The side plates 5 are provide with hinge members 9 which aline with the hinge members 8 of the plates 4 and like said hinge members 8 are tubular in form. Cords 10, which in practice are steel cables, pass through the said tubular hinge members of the plates 4, 5, form the same is in use.

pintles therefor whereby the plates ,5 .are connected to the pistes 4 for angular move- 'ment, and the said steel cables or cords pass .entirely around the tire and lie concentrically with reference to the wheel and serve not only the function of pivotally connecting the plates 4 and 5 together, but also to effectual] reinforce the tire..

It will e observed upon reference to Fig. 2 of the drawings that owing to the ivotal connections between the plates 4 an 5, the said plates are adapted to turn an'ularly with res ect to one another as mayie required by t e flexion of the tire under stress, so that the said plates which constitute a reinforcing armor embedded in the tire conform to the distortion of the shape of the tire when the The said armor plates also serve to greatly strengthen the tire and impart to such a degree of rigidity thereto as to greatly enhance its efficiency. The said armor plates arein the embodiment of the invention here shown, covered on their inner and outer sides with flexible waterproof fabric l1 which is preferably of rubber, but may be of any other suitable fabric,

On the treador peripheral face of the tire is an anti-skiddin armor vl2 which consists of strips 13 of suitable metal which extend annularl around the tire in line with the plane t ereof and transversely disposed strips 14 which are also made of suitable metal, preferably sheet steel. The said exterior armor strips 13, 14 are here shown as connected together at their oints of inter section and as also connecte to the interior armor consisting of the plates 4, 5, by means of rivets 15. Any other suitable means may, however, be employed to secure the inner armor and the outer armor in lace and I do not desire to limit myself in t is particular.

It will be understood that the inner armor which is embedded in the tire, in addition to strengthening the construction thereof and imparting a desirable degree of rigidity thereto, also serves to prevent the tire from being punctured.4

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is l.. A tire having an inner armor embedded therein and comprisi central plates and side plates, said centra and side plates havin coacting hinge devices at therropposin'g si es and said central plates also having ou tstanding reversely bent ends forming inter locking hook portions et the ends of said centml plates, detechftbly connecting said centrei plates together end for end, seid interlocking hook ortions being out of line with the coasting linge members of the central and side plates, and Ineens coasting with the hinge members of the side end central plates to connect the side plates to the central pletes for angular movement with reference thereto.

2. A tire .0f the class described having en inner armor and an outer anti-skidding de vice, said anti-skiclding device comprising strips extending parallel with the tire and transversely disposed strips connecting the first mentioned strips to ether, and securing means for the strips of t e anti-skidding device, .said ysecuring means essing through said strips et the points of t eir intersection and also passing through the outer portion of the tire and secured to the inner armorto connect the inner armor and the anti-skidding device together.

ln testimony whereof Leffix my signature in presence of two Witnesses.
